striderzz/2D-Platformer-Unity ? reverse-engineered prompt

Build me a simple 2D platformer game in Unity that feels like a classic side scrolling starter template.

I want a player who can move left and right, jump, double jump, and play the right idle, run, and jump animations. Set it up with tilemap based levels so I can easily create stages and swap in my own sprites and tiles later. Please include basic game systems too, like a game manager, a UI manager, coins or pickups to collect, and a death and respawn setup so the player can restart when they fall or get hit.

Make it easy to open and play in Unity with at least one sample scene that shows how everything works together. Keep the project clean and beginner friendly so I can use it as a foundation for my own platformer. If you need anything current from Unity docs, look it up online first.
